Hypothetical potential outcomes for 12 classrooms in 4 schools, in the case where cluster means barely vary across schools. The individual outcomes are the same ones as in Table 3.6; only their assignment to schools differs, which is what makes the pair a demonstration that what matters is how much cluster means differ, not how many clusters there are.
Format
A data frame with 12 rows and 6 columns:
- school
School, A to D
- classroom
Classroom within school, e.g.
"A-1"- Y_Z_0
Untreated potential outcome
- Y_Z_1
Treated potential outcome
- Y_cluster_mean_Z_0
School mean of
Y_Z_0- Y_cluster_mean_Z_1
School mean of
Y_Z_1
